Cardiac Monitoring · Extended Holter
Fourteen days of Holter. Thirty-three grams.
The DR400 is the smallest and most versatile monitor in the NorthEast Monitoring line-up. Weighing just 33 grams, the showerable 3-lead patch-style recorder captures up to fourteen days of 3-channel Holter on a single charge — without asking the patient to carry anything or change how they live.
Three channels, continuously, for up to fourteen days.

Compact, powerful, exceptionally versatile
Built for the demands of remote cardiac diagnostics — from hospitals to home settings — without trading away patient comfort.
- Holter monitoring
- 30-day event monitoring
- Pharmaceutical studies
Up to 14-day 3-channel Holter
Continuous recording for the full study window on a single charge of the internal lithium battery.
2- or 3-electrode patch
Electrode configuration chosen to match the clinical question.
Showerable (IP44)
Water resistant, so the study survives a normal week.
Docking station
Charges the recorder and connects it to a PC for data transfer.
PCPatch utility
Easy study setup and data transfer from the office PC.
Wireless ECG at startup
View the ECG as the study starts to confirm a clean signal before the patient leaves.
The software behind it
A recorder is only half of it
